SketchUp (formerly Google Sketchup) is a 3D modeling computer program for a wide range of drawing applications such as architectural, interior design, civil and mechanical engineering, film, and video game design—and available in a freeware version, SketchUp Make, and a paid version with additional functionality, SketchUp Pro.

ZBrush Overview

LuxRender is a physically based and unbiased rendering engine. Based on state of the art algorithms, LuxRender simulates the flow of light according to physical equations, thus producing realistic images of photographic quality.

The Persistence of Vision Raytracer is a high-quality, totally free tool for creating stunning three-dimensional graphics. It is available in official versions for Windows, Mac OS/Mac OS X and i86 Linux. The source code is available for those wanting to do their own ports.

Clara.io is a full-featured cloud-based 3D modeling, animation and rendering software tool that runs in your web browser.

KeyShot is an interactive raytracing and global illumination program developed by Luxion for both PC and Mac that breaks down the complexity of creating photographic images from 3D models.

PhotoRealistic RenderMan, or PRMan for short, is a proprietary photorealistic RenderMan-compliant renderer.

Cycles is Blender’s ray-trace based production render engine and in development since 2011. It was originally developed by Brecht van Lommel, and is maintained by an active team of developers today. Since its release as Apache 2.0 (permissive open source), it’s also in use by other 3D tools, such as Poser and Rhino.

Powerful, feature-rich and fast standalone raytracing renderer.

A free Terrain Synthesizer and RendererPicogen is an outdoor ray tracing system, a free Terrain Synthesizer and Renderer targeting large-scale terrain with realistic day/night-illumination and detailed plant populations.

appleseed is a modern, open source, physically-based rendering engine designed to produce photorealistic images, animations and visual effects. It provides individuals and small studios with an efficient, reliable suite of tools built on robust foundations and open technologies.

Sunflow is an open source rendering system for photo-realistic image synthesis. It is written in Java and built around a flexible ray tracing core and an extensible object-oriented design. It was created as a framework for experimenting with global illumination algorithms and new surface shading models.Current Features:
